Specification of Letters Patent.

Patented Dec. 1, 1914.

Application filed November 18, 19.12.` Serial No. 732,029.

To all whom it may concern Be it known that I, JOSEPH Ewen, a citizen of the United States, residing at Chicago, in the county of Cook and State of a certain new and useful Improvement in Radiators, of which the following is a specification.

This invention relates to improvements in radiators and has for its object to provide a lo new and improved device of this description.

This invention is particularly adapted for radiators used in connection with steam heating. In suchradiators it is found that air accumulates in the radiators and preoperation thereof by interfering with the proper movement or circulation of the steam and by reducing the effective heating area. It is customary to provide each radiator with an air valve air escapes from the radiator.

One of the objects of the present invention is to provide a radiator which can properly take care of the air without the need of as such valves have many defects and objectionable features.

l The invention is illustrated in the accompanying drawings wherein- Figure l is a view of a radiator embodyshowing one method of connecting the air tube in position.

Like numerals refer out the several figures. J Referring new to Fig. l, I have shown a 'radiator l made up of a series of sections connected together at the top and bottom. i The steam enters the radiator through the supply pipe 2. The radiator is also pro` Located between the first section 4 and the adjoining section 4a of the radiator is an obstructing device 5 provided with a comparatively small central opening 6. Connected with is opening G is a pipe 7 which extends into the section 4 of the radiator and partway therealong and is open at the end. This pipe is of mate-rial which is a good conductor of heat and is preferably metal such as 9 copper or the like. It is, of course, evident that any desired form of obstructing device may be used and any form of pipe may also be used, and when I use the word pipe in the specification and claims, I mean to ini clude a pipe tube or conveying device for the air of any desired shape and cross section.

to like parts through- This construction forms an air circulating device inclosed `within the radiator by means of which the aill in the radiator is re-heated and circulated when the radiator is in operation.

When the device is in operation, the steam passes through the admission pipe 2 into the section l of the radiator. This steam then passes up along said section and along the tube or pipe 7 to the top of the radiator. The steam heats the air in the tube or pipe 7, thus making it lighter so that it flows up through the pipe and mingles with the steam, the colder air being drawn through the pipe and obstructing device 5, and thus a circulation in the radiator secured. The air in the radiator gradually escapes through the return pipe 3. As the air is heavier than the steam, it will sink to the bottom of the radiator and be drawn up, as it were, through the pipe 7. As the air which is always mingled with the steam tends to accumulate in the radiator, it drops to the bottom and is drawn up through the pipe 7 and reheated and mingled with the steam and thus kept in circulation while inthe radiator and gradually passes out through the return pipe 3. It will be seen that by means of this construction the banking of the air in any particular part of the radiator is preventedf and the cooling of the air so as to shut off that part of the radiator is also prevented as the air is kept heated and kept in circulation until it passes ont through the return pipe 3. It will further be seen that no air valve is necessary and that the radiator is completely closed so that no steam, water or air can escape into the apartment.

I claim:

l. The combination with a radiator having a series of sections connected together at the top and bottom, of an obstructing device located between two of the sections at the bottom thereof, said obstructing device provided with an openingand an air circulatin pipe extending upwardly on the inlet si e of the obstructing device part way along one of said sections and extending into the opening of the obstructing device.

2. The combination with a radiator havi inga series of vertical sections connected together at the top and bottom, of an obstructing device between two of said sections at said bottom connection and a pipe extending part way along one of said sections on n the inlet Side of said obstructing device, said pipe communicating With the remaining portion of the radiator on the other side of the obstructing device.

3. The combination with a radiator Vhaving a series of sections connected together at the top and bottom, of an obstructing devic'e between the first and Second sections at the said bottom connection, said obstructing device provided with an opening, a pipe extending part Way along the iirst section, said pipe mounted upon said obstructing device and communicating with the `other section through the opening in said obstructing device.

4. The combination with ing a series of sections connected together at the top and bottom of an obstructing dea radiator havi vice between two of said sections at the bottom thereof, said obstructing device provided with an opening, an air circulating pipe vextending partivajv along one of said sections and mounted upon said obstructing device and communicating With the adjecent section through the opening in said obstructing device, the tion and tie air in said air circulating pipe tiovving in the same direction when tbe radi ator is in ope-ration.

In testimony whereof, aiix my signature in thepresence of two witnesses this 12th day of November i912. f
